| JBL ProFlora Safe Stop is a special non-return valve for COČ. Non-return valve with washer, pre-tensioned by a spring, preventing water leaking into the pressure regulator and COČ cylinder. COČ has a very powerful diffusion strength which, if a normal non-return valve was used, would draw water from the aquarium through the valve as far as the storage cylinder. |
